CAR-AXLE-BOX OILER.

SPECIFICATION formingpart of Letters Patent No. 236,057, dated December28, 1880. Application filed October 8, 1880. ('No model.)

To all whom it may concern Be it known that I, JAMES D. Mnnnrrr, of thecity, county, and State of New York, have invented certain new anduseful Improvements in Gar-Box Oilers, of which the following is aspecification.

Myinvention relates to car-box oilers which consist of metallic skeletonframework covered.

with woolen.

The invention consists in a novel construction of an elastic wiper,which is pressed up against the axle on the outside of the oiler andprevents the passage of oil outward, as well as the passage of dust anddirt inward.

It also consists in the combination, with a shaft adapted to be rotatedby frictional contact with the axle, of a novel form of lapper and swabfor oiling the axle.

It also consists in the combination, in an oiler with the metallicspring pads adapted to bear upon opposite sides of theaxle and providedwith perforations th rough which oil may run back into the box.

It also consists in the combination, with a rotary shaft and attachedmetallic lappers and swabs, of a metallic shield or guard-plate, toprevent the metallic lappers from wearing out the woolen covering at thebottom of the oiler.

In the accompanyingdrawings, Figure 1 represents a plan of an oilerembodying my inven t-ion. Fig. 2 represents an end view thereof; andFig. 3 represents a transverse section upon the dotted line aa", Fig. 1.

Similar letters of reference designate corresponding parts in all thefigures.

The frame-work of my oiler is composed 'of longitudinal rods or bars A,A, and A and cross rods or bars A which unite the rods or bars AA uponopposite sides of the oiler.

At each end of the frame is a bent spring or springs, B, which arecomposed of wire, and which tend to raise or expand the frame in avertical direction. The frame work of the oiler is surrounded orconcealed by a woolen covering, a, which excludes any dirt which may getinto the axle-box.

Extending across the front end of the oilerframeis a wiper, O, composedof a spiral spring, I), connected at each end to the metallic frame, butotherwise unsupported, and a woolen covframe-work, of

ering, which is extended down the front in a flap, b, the capillaryattraction of which will draw up oil, and down which the oil will run tothe lower part of the box. This wiper prevents oil from running upon theaxle outside the box, and prevents the entrance of dust and dirt.

In order to properly guide the oiler and adapt it for car-boxes ofvarious sizes, I construct the frame with outwardly-projectin g arms,rods, or ears, 0, which may be of considerable length, and be cut oil"so as to suit boxes of different sizes. \Vhen out to the proper lengththese rods, arms, or cars form guides to prevent the lateral movement ofthe oiler in the axle-box.

I) designates a spindle or shaft, which is free to rotate in bearin gsattached to or formed in the cross-bars A and to which are fixed smallwheels, D, which are packed with leather --or other material at theperiphery, and are adapted to be rotated with the shaft by frictionalcontact with the axle.

To the spindle or shaft D are attached metallic lappers (I, made in theform of loops, and carrying at the open ends swabs e, of woolen or othersoft material, which, as the spindle or shaft is rotated rapidly by therotating axle, take up the oil and throw it upon the axle. The lappersd, made in the form of loops, are very desirable, as their open roundedfree ends will, when drawn through the oil,

raise the oil with much greater rapidity than would straight lappers,such as bristles or hair. Then the frame of the oiler is contracted bythe weight of the axle the metallic lappers cl will strike upon thebottom of the oiler; and, to prevent the woolen covering from beingrapidly worn through, I attach thereto a sheet or plate metal guard orshield, E, upon which the lappers bear.

F designates pads attached to the upper part of the frame upon each sideof the axle, and upon which the axle bears. These pads are provided withdownwardly-extending flaps f, which draw up the oil by capillary actionand saturate the said pads. In order to check the flow of oil when thesepads become dry and glazed, I make in them perforations g, through whichthe oil may return into the box.

By my invention I provide for uniformly oiling all parts of thejournals, and produce an oiler from which the oil cannot readily escapenor dust and dirt enter.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, with themetallic framework, of the elastic wiper O,composed of a spiral spring, I), attached at each end to saidframe-work, but otherwise unsupported, and a woolen covering" for saidspring having a flap, 1), extending therefrom, substantially asspecified.

2. The combination, in a car-box oiler, of a shaft, and friction-wheelsattached thereto and adapted to bear upon the axle, one or more wirelappers fixed in said shaft and bent to form loops at their free endsand swabs upon the loops of said lappcrs, substantially as specified.

3. The combination, with the metallicspring frame-work of a car boxoiler, of pads F, adapted to bear upon opposite sides of an axle, andconstructed with perforations g, substantially as and for the purposespecified.

4. The combination, with the frame-work of 2 5 J. l). MERRITT.
